In this study, Damar Batu (DB) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. DB is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (Mw), polydispersity index (Mw/Mn) and glass transition temperature (Tg). Neat plasticized films of DB are investigated for mechanical, water vapor transmission...
Background: Edible films and coatings are biodegradable that can preserve the quality and extend the shelf life of foods. The aim of this study was to investigate the physical and mechanical properties, and antimicrobial activity of carboxymethyl cellulose (CMC) film containing Artemisia sieberi Essential Oil (AEO). Methods: The studied parameters were the antibacterial activity and physical p...
Abstract: Different thickness of Cu2S thin films were prepared by vacuum evaporation under a pressure of 10-6 torr at an evaporation rate of 3Å /sec. Cu2S has direct band gap energy and indirect band gap energy at 1.2eV and 1.8 eV respectively. This paper presents the analysis of structural and optical properties of the Cu2S thin film by X-ray diffractometer (XRD) and UV-Vis-NIR Spectrophotomet...
The conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. A novel nano-Au/poly (4-aminobenzoicacid) (PABA) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. The PABA film and nano-Au/PABA film were characterized by scanning...

To apply the nanomaterial as a component in the packaging material structure, in this research, the carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared with three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film wa...
The carboxymethyl cellulose (CMC)/polyvinyl alcohol (PVA) film were prepared by adding three levels of nanoclay particles (0.5, 1 and 3%) using solution casting evaporation method. The incorporation of nanoclay on mechanical, water vapor permeability, and oxygen barrier properties of CMC/PVA-based film was investigated. The best result was obtained through the nanocomposite film contain 3% nano...
zinc oxide nanoparticles have been synthesized by chemical reaction method. polyvinyl alcohol (pva) composite film filled with nanometric, monodispersed zinc oxide nano particles prepared by pva solution and nanozinc oxide. polymer blend with zno nanoparticle composite film has prepared by casting technique. the property of nano composites depends greatly on the chemistry of polymer matrices....
The transition metal nitrides like titanium nitride exhibit very interesting color variation properties depending on the different plasma deposition conditions using cylindrical magnetron sputtering method. It is found in this deposition study that nitrogen partial pressure in the reactive gas discharge environment plays a significant role on the color variation of the film coatings on bell-met...
